Note 1: When the DAMP board is replaced, spread the
compound referring to "NOTE OF REPLACING
THE IC1001 ON THE DAMP BOARD AND THE
COMPLETE DAMP BOARD" on servicing notes
(page 5).
Note 2: When the DAMP board is replaced, spread the
bond referring to "BOND FIXATION OF ELECTRIC
PARTS" on servicing notes (page 6).

• 2 : nonfl ammable resistor.
• C : panel designation.
Note: The components identifi ed by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specifi ed.

• B : B– Line.
• H : Adjustment for repair.
• Voltage and waveforms are dc with respect to ground

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
